As an attending physician in the Cancer Center, Section Chief of the Cellular Therapy and Transplant Section, Director of the Cancer Immunotherapy Program, and the Medical Director of the Cell and Gene Therapy Laboratory, I take on many roles here at CHOP. But in each of them, I’m a pediatric oncologist working to improve outcomes for children battling difficult cancers. I received an M.D. and Ph.D. from the University of Cincinnati College of Medicine and completed residency and fellowships at Harvard Medical School, Boston Children’s Hospital, Dana Farber Cancer Institute and Brigham and Women’s Hospital, before coming to CHOP in 1996.
T cells have the potential to kill cancer cells, but in patients with cancer, they’re not doing that job. By genetically modifying them, we can make the cells behave differently so they’ll attack cancer cells, using an engineered targeting protein called a chimeric antigen receptor (CAR). Working with our colleagues at the University of Pennsylvania and later with Novartis, we have developed CAR T therapy for children with ALL, opening up a brand new field of medicine and resulting in the first global approval of an engineered cell therapy and also the first gene therapy approved in the US. During the development of this product, I was honored to run the initial CHOP phase 1 trial, the first US multicenter trial of a CAR T therapy, the first international trial (sponsored by Novartis), and the first CAR T pivotal trial. This work has now been extended to using these genetically modified CAR T cells to treat patients with other B cell cancers such as B cell non-Hodgkin lymphoma (NHL), the adult disease chronic lymphocytic leukemia, and other B cell malignancies. In addition to FDA and global health authority approvals, this work has received international attention, generating dozens of high impact scientific publications, including three in the New England Journal of Medicine.
Exciting trials just opening or in the immediate CHOP cell therapy pipeline will extend these results to AML, new forms of ALL, and (coming soon) pediatric solid tumors, providing options for patients with no other therapies available.
Using similar approaches, and working with our colleagues in the Division of Hematology and the CuRED program, we now have multiple clinical trials testing ways to genetically modify bone marrow stem cells to cure diseases like sickle cell anemia and thalassemia. Over 100,000 patients in the US suffer from these red blood cell disorders. This illustrates the commitment of the CTTS to cure patients with cell therapy that have life-threatening, but non-cancer, diseases. Over the past 20 years, our Transplant group has evolved to the point where half the transplants we do are for non-cancer diagnoses.
In one of my clinical roles, I also work with patients with the most aggressive form of neuroblastoma, a difficult-to-treat childhood cancer that begins in the peripheral (non-brain) nerve tissue of infants and young children. I work alongside a world-class team of physicians and multi-disciplinary specialists who are dedicated to treating this disease. The tandem transplant approach that is now standard of care across the country was developed by our group here at CHOP. In addition, the neuroblastoma team at CHOP does studies of the patient’s genetics and the unique characteristics of their disease to offer a personalized treatment approach. We also were part of the group that did the nationwide clinical trial establishing antibody-based immunotherapy as the new standard of care in neuroblastoma.
In the lab and the hospital, I am a lab scientist, a cell therapist, and a stem cell transplanter. In the Cell and Gene Therapy Laboratory, we collect cells for transplant and CAR T therapy and manage cell processing: both collecting the original cells and engineering the cells so the right cell type gets into the patient.
What first brought me to CHOP was the opportunity to conduct transplant and leukemia research, and work in CHOP’s intensely translational environment. Today, I run a lab where the research is devoted to developing cell-based and molecularly-targeted therapies to treat leukemia and solid tumors. The goal of all the work I do is to improve treatment options for children with cancer, not just at CHOP but throughout the world. Whether that’s accomplished by offering alternative therapies that are less toxic than today’s standards of care, advanced treatments for high-risk disease that fight cancer in new and different ways, or cures for genetic disorders like sickle cell, if we impact the standard of care I consider that a success.

Patient Experience Ratings
About the Patient Experience Rating System
The Patient Experience Rating is an average of all responses to the care provider related questions shown above from our nationally-recognized Press Ganey Patient Satisfaction Survey. Patients that are treated in outpatient or hospital environments may receive different surveys, and the volume of responses will vary by question.
Responses are measured on a scale of 1 to 5 with 5 being the best score.
We are committed to true transparency. However, to ensure the comments are fair and correctly attributed, we review each one before posting to the website. We exclude entire comments that disclose patient's protected health information, are off-topic, or include other confidential or inappropriate content. Comments will appear on provider bios only if providers have a minimum number of comments.
Comments are shared internally for education purposes to ensure that we are doing our very best for the patients and families for whom we are privileged to care.
The comments are submitted by patients and families and reflect their views and opinions. The comments are not endorsed by and do not reflect the views of Children’s Hospital of Philadelphia.
